SPTNNING-FING HOLDER.

Specification of Letters Patent. Application med September 24, 1910. suitin 583,545.

Patented SeptlS, 1914.

New' Hampshire, have invented an Improvement in S inning-Ring Holders, of

which the following description, in conneo tion with the accompanying drawing, is a specification, like characters on the drawing plate is provided with a guiding projection representing like parts.

- This invention relates to spinning ring holders of that type which are detachably se- F cured to the ring rail or rail plate so that the spinning ring holder'with its spinning ring can be readily removed from the-rail plate without disturbing the latter to permit another spinning ring holder with its spinning ring to be substituted therefor.

The objects of .the present invention are to provide a novel way of detachablyfastening the spinning ring holder to the rail plate, all as more fully hereinafter described and then pointed out in the appended claims.

Referring to the drawings wherein I have shown one embodiment of my invention, Figure 1 is a plan view of a portion of a ring rail equipped with my improved spinning ring holder; Fig. 2 is a plan view. of a rail plate adapted to receive my improved spinning ring holder; Fig. 3 is a plan view of the spinning ring holder detached; Fig. 4 is a side view of the spinning ring holder applied to the rail plate; Fig. 5 is a side view of a portion of the opposite side of the spinning ring holder and rail plate from.

that shown in Fig. a; Fig. 6 is an enlarged section on the line bb, Fig. 1.

In the drawings 3 designates a ring rail f any suitable construction which is provided with the usual apertures 4: through which the bobbin extends. Spinning rin s of this type as now commonly made usually employ a rail plate which is secured to the ring rail 3 and is provided with an aperture concentricwith the aperture 4:, and a ring holder which supports the spinning ring andwhich is secured to the rail plate. As stated above, onefeature of my present in vention relates to a novel manner, of-secur-- ing the ring holder to the rail plate.

In the drawings a rail plate is shown at 5 and it is provided with the aperture 6- concentric'with the aperture 4: and is adapted to be'secured to the ring rail 3 by any suitable means, such as screws 7. Thering holder is shown at 8 and it is provided with a central aperture as usual and ;-'is also provided with upturned ears or lips 9 which engage thelower flange of the 'usual spinning ring ,1O this being a common: method of fastening the spinning ring-to,;. the'ring holder. =In the presentimprovement the rail jection. The guiding projection is shown at 11 and it is herein illustrated as being formed by cutting and bending up a portion of the rail plate adjacent the edge thereof although such guiding project-ion. might be situated at a distance from said edge without departing from the invention. In the preferred embodiment of my invention the end of the material which forms this guiding projection is bent over to formthe lip 12 which liessubstantially parallel. to the rail plate. The opening in the. ring holder adapted to receive the guiding projection is herein shown at 13 and is in the form of a notch formed in the edge of the ring holder,

but this opening would, of course, have a position corresponding to that of the guiding projection.

The locking member is preferably situv is turned laterally about the guiding' proated on the opposite side of the rail plate from that of the guiding projection, and it is herein illustrated as in the form ofa looking finger 14 which extends parallel to the rail plate and beneath which the ring holder may pass and which is provided with a lock ing projection or point 15 that is adapted to engage an aperture or indentation 16 formed in the ringholder. This locking member may conveniently be made by slitting the ring rail and bending the. slitportion up to the proper shape. The ring holder is provided with an opening or notch 17 which is situated so that when the ring holder is applied to the rail plate the locking member 14: will pass through the-notch so as to be situated above said ring holder. applying' the ring" holder to the rail plate the guiding projection 11 is slipped into the notch or opening 13 and the ring holder is then posiltiorie'd so that the notch 17 therein will be located in' aline'ment with the locking mem- -=iberl= and said ring holder is dropped onto 'the' rail plate, thuspermitting the locln'ng member to pass-through the notch or 0 ening 17, asshownin" dotted lines Fig. 1. he ring holder is then swung laterally-about the guiding projection 11 as a centerdurin'g' whichmovement the portion 18 of the ring holder adj acent the notch 7 passes under the 15 lockingrnember 14 and when the shoulder or ed $19 of the notch 17 brings up against the vertical portion 20 of the locking menu-- the ring holder will be properly posi- 1 tio'ned' concentriewith the rail plate. The; 2;) locking member may be so constructed that the frictional engagement between it and the uppersurface of'the ring holder will hold-the latter in its adjusted position, but

prefer to make the locking member .with the locking point 15 as above described which snaps into the indentation. 16 and thus more securely holds the ring holder in position.v ,The ring holder can be readily detached by swinging it laterally about the x guiding. projection as a center into the dotted line position Fig. l andthen moving it verticallyaway from the rail late to carry the rim holder above the loc g members i 14.- 23 indicates a traveler-clearer. 85 While I have illustrated herein the preferred embodiment of myinvention I do not wish to be limited to the constructional details shown.

Ha'ving fully described my invention, 7

what I claim as new and desire to secure by Letters Patent is:--

1. In a spinning ring, the combination with a rail plate having a guiding projection and a resiliently sustained locking memher which extends parallel to the upper face of the rail plate, of a ring holder having an opening to receive the guiding projection and adapted to turn laterally about said guiding projection as a center and having another opening to receive the locking member whereby when the ring holder is turned laterally about the guiding projection a portion-of the ring holder will pass beneath the resiliently-sustained locking member andv be frictionally engaged thereby.

2. In a spinning ring, the combination with a rail plate having aguiding "jproj ection and a lockin member WhlCh extends parallel thereto, 0 a ring holder having an opening to receive the guiding projection and adapted to turn laterally about said guiding projection as a center and having another opening to; receive the ,locking member whereby when the ring holder is turned 1at- .erally about the guiding projection a portion ofthe ring holder will pass beneath the locking member,.said locking member having. alocking lip adapted to enter a recess in the ring holder when the latter is properly positioned.

, In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
